General AI assistant · Checked 7 November 2026
Ziva vs ChatGPT for tenders and RFPs
ChatGPT, from OpenAI, is the most widely used general AI assistant, and its Business and Enterprise plans add connected apps, ChatGPT Work for multi-step tasks and admin controls. Ziva is built for one job: winning tenders. She finds the opportunity, qualifies it on the full package, answers from your approved knowledge with citations, runs review, and returns the buyer’s own files finished. Many bid teams use both.
Choose Ziva if
Tenders and RFPs are a recurring revenue channel, several people review each bid, and the output has to be the buyer’s own Excel and Word files with every claim traceable to your evidence.
Keep ChatGPT alone if
You want one assistant for writing, research, analysis and agent tasks across the company, and tender work is occasional enough that people can search portals, track review and assemble files themselves.
What Ziva watches for you
ChatGPT starts when someone uploads a tender. Ziva starts at the portal.

Isolation
Every Project gets its own isolated virtual machine.
The machine belongs to the Project, not to a person. Everyone on the bid works in the same workspace with the same files, whoever opened it first. Customers never share a machine, and you choose where your organization is hosted.

Kept outside the machine. Files, versions, answers and every conversation are stored durably, so work survives when a machine is replaced.
Controlled access out. No passwords or cloud keys inside the machine. It reaches only approved services: your company knowledge, web research when you turn it on, and connected apps that ask before they change anything.
Another customer
Own organization, own Projects, own machines. Nothing is shared between customers.

ChatGPT Work administrator FAQ(opens in a new tab)ChatGPT Business(opens in a new tab)What Ziva brings to every bid
Your company’s way of bidding, remembered.
Organization skills
Teach Ziva how your company writes a method statement or prices a lot once. She follows that skill in every Project, and can propose new skills when she spots a repeatable pattern.
Organization memory
Facts, tone, terminology and formatting rules are remembered across Projects, each with the date it was last updated, so Ziva can tell fresh knowledge from stale.
Connected apps
Notion, Atlassian and GitHub, and SharePoint where your admin sets it up. Each user connects them and turns them on per message, and Ziva asks before any change to an external system.
Web research when you want it
Off by default. Turn it on for one message when you need current outside facts, and the answer keeps its source links.
More than 100 languages
Search and answer across languages without a translation step, so a German tender can draw on English evidence.
Live awareness of the bid
Ziva sees which answers are approved, which reviewer still has to sign off and what they commented, as the team works.
Credit where it is due
What ChatGPT does well.
ChatGPT is a better choice than Ziva for most work that is not a tender. These are its real strengths.

Writing, research, analysis and deep research for almost any task in the company.

A fresh perspective and a sparring partner
Our bid experts look at the tender from outside and argue pursuit, positioning and bid strategy with you.
- 2
Buy-side and sell-side experience
People who have written and evaluated tenders. They know how much of a framework is realistically called off, so bid time goes where the budget is real.
- 3
Your effort falls with every tender
Zelius learns your company with each bid. You give only what only you can: missing facts, price decisions and the signature.
- 4
References and partners
Zelius takes the reference work off you, including drafting the requests to your clients, and can introduce co-bidders and subcontractors from its network.
When to use which
Most bid teams use both.
Use ChatGPT for
- Writing, research and analysis across every department
- Agent tasks with ChatGPT Work and code with Codex
- One-off questions about a document you already have
Use Ziva for
- Finding and qualifying tenders every week
- Answering a full tender from approved, cited company knowledge
- Review with named approvers and the buyer’s files returned finished
Use both like this
Draft a cover letter idea or summarize a market in ChatGPT, then bring it into the Ziva Project where it is cited, reviewed and placed in the buyer’s template.
Keep ChatGPT as the company assistant and give the bid team Ziva. Every Ziva plan includes unlimited users, so legal, finance and subject experts review without a seat budget.
Questions
Ziva vs ChatGPT: straight answers.
Can ChatGPT answer an RFP?
Yes, ChatGPT can draft answers from files and connected apps, and ChatGPT Work can create documents. What it does not do on its own is find tenders, keep an approved answer library with citations and confidence, track review per answer, or fill the buyer’s workbook in place. Ziva does those as part of the bid.
ChatGPT Work administrator FAQ(opens in a new tab)ChatGPT connected apps(opens in a new tab)Does ChatGPT find public tenders?
We found no built-in tender discovery in ChatGPT’s plans. Ziva Intelligence searches connected procurement portals across many countries every week and qualifies what it finds.
ChatGPT plans and pricing(opens in a new tab)ChatGPT Business(opens in a new tab)Is my data used to train models?
OpenAI states that ChatGPT Business data is never used for training, and offers data residency through sales. Ziva never uses customer data to train models and offers hosting in Switzerland, the EU or the US.
ChatGPT Business(opens in a new tab)How do users and pricing compare?
ChatGPT Business is priced per user from 2 users, and Enterprise is sold through OpenAI sales. Ziva is priced per project with unlimited users, so reviewers and subject experts never need a seat.
ChatGPT plans and pricing(opens in a new tab)Can we use ChatGPT and Ziva together?
Yes. Many teams keep a general assistant for everyday work and run tenders in Ziva, where answers are cited, reviewed and delivered in the buyer’s format.
Sources and method
We read OpenAI’s own plan, product and help pages on 7 November 2026 and compared the Business and Enterprise plans. Where we could not confirm a feature on an official page, we say that we did not find it rather than guess. Tender counts come from our live Tender Universe statistics and carry their own time. Zephior publishes this page and sells Ziva. If anything about ChatGPT has changed, tell us at hello@zephior.com and we will correct it. Product names belong to their owners.
